holland's scope level 35mm tube

Holland's Scope Level 35mm (tube size). They are machined from 7075-T6 aluminum and hard black anodized. These scope levels are without a doubt the most attractive, well designed level you can buy. They feature a hole for attaching your data card to the rifle. Most importantly they can be seen from a firing position, say goodbye to "turkey necking" to check for reticle perpendicularity.
